my 9 month old daughter has had a coughfor over 3 months she has not gained weight in that time has been very sick on and off, sometimes she is sick 6 -9 nights on the bounce and it seems more comes up than goes in,she also does not seem to be growing she has a rash all over her face and under her eyes which makes her look really ill, the cough is very mucusy but and is always at night time and after sleeps although she does cough in the day its just not as bad,her pooh smells vile and she is very grumpy and clingy she does not taste salty. we have tried inhalers and antibiotics but nothing has helped can anyone help with this
